The World of Orchids

With an estimated 25,000 species worldwide, orchids are loved for their exotic and mysterious habitat, from cloud-shrouded mountains and rainforests, to mangrove swamps and semi-desert scrubs. They are perhaps the most challenging of all flowering plants to cultivate outside their natural habitat, often taking many years before the first flower appears.

The World of Orchids: A Practical Guide to Cultivating Orchids in Soilless Culture, by Jack Ross, is now available as a download eBook at a good price. This book presents the results of the author’s many years of research into orchid cultivation using soilless culture techniques. It is for orchid enthusiasts as well as commercial growers producing high quality orchid plants. –

What is ‘false drain’?

September 11, 2017
Hydroponic expert Rick Donnan

Higher ECs within the medium than in the runoff

I have been growing tomatoes in rockwool slabs for over three years. Recently, my plants have been looking stressed and I have had some blossom end rot.

Friends have suggested that it might be high EC in the slabs, but my run-off EC (electrical conductivity) is usually below 3 (mS/cm).

At their suggestion I recently bought a WET (Water, EC, Temperature) meter to measure properties within the slab. I now find that I am sometimes getting much higher EC readings within the slab than in the drain. Is this normal, and what should I do?
